The context in Nivelles
Why here in particular
A historic town dominated by the Saint Gertrude collegiate church, Nivelles combines an old centre rebuilt after the war with wide outlying districts. In practice the old centre sets constraints on colour and material: we always check before ordering a roof covering.
A roof window that leaks is almost never the window: it is the flashing. A sealing kit that does not match the type of roof covering, and water gets through the first winter that comes.

Frequently asked questions
Velux roof window installation in Nivelles
The questions we get asked most often before this kind of job.
Can it be applied to a slate roof?
Yes, with the matching flat flashing kit. The kit is not the same as for a profiled tile.
And condensation?
It comes from a lack of ventilation, not from the window. A reveal cut square at the top and sloped at the bottom lets air circulate against the glazing.
Do you replace an existing roof window?
Yes, and it is often half a day: the new frame takes over the existing opening when the dimensions match.
Do you come out to Nivelles with no extra call-out charge?
Yes. Nivelles is one of our 17 municipalities: the call-out is included in the quote, not added at the bottom of the invoice.
